Problems solved by technology

Although its structure is simple, its heat insulation effect is insufficient, and it does not have automatic temperature monitoring, recording or alarming. Whether the shell or the insulation layer is damaged, it is very troublesome to replace and repair, and the cost is high. Moreover, after the insulation box is sealed, The gas in the box is in a non-flowing state, and it cannot effectively control the temperature of food, medicine, etc. that need to be kept at a certain temperature, which will cause product quality damage and use

Abstract

The invention discloses an intelligent temperature control early warning food security insulation box. The intelligent temperature control early warning food security insulation box comprises a box body, an upper cover and an insulation inner cavity formed by the box body and the upper cover; the box body and the upper cover are each sequentially provided with a shell, a vacuum thermal insulation layer and a cavity wall from exterior to interior; the inner side of the upper cover is provided with a pressing sheet, and the pressing sheet is connected with the upper cover through a spring; the longitudinal direction and the transverse direction of the inner wall of the box body are each provided with an elastic fixing belt, and therefore objects can be fixed in a cross traction mode after the object is well put into the box body. The intelligent temperature control early warning food security insulation box is used for solving the defects in the prior art, a detachable support air channel is arranged in the shell of the box body, the maintenance is facilitated, the air flow in the thermal insulation inner cavity is enhanced, and the thermal insulation effect of the objects is improved.

Description

technical field [0001] The invention relates to the field of heat preservation equipment, in particular to an intelligent temperature control and early warning food safety heat preservation box that can automatically monitor the temperature in the box. Background technique [0002] Existing heat preservation boxes generally consist of a shell and an insulation layer inside the shell. A cold source or a heat source is arranged in the heat preservation chamber, and heat insulation materials are often used for the heat insulation layer. Although its structure is simple, its heat insulation effect is insufficient, and it does not have automatic temperature monitoring, recording or alarming. Whether the shell or the insulation layer is damaged, it is very troublesome to replace and repair, and the cost is high. Moreover, after the insulation box is sealed, The gas in the box is in a non-flowing state, and it cannot effectively control the temperature of food and medicine that ne...
